SD

Super-deformed. In anime and manga, when a character is drawn cartoonishly short, about 3 heads high and has deexagerated limbs (i.e. having mitt-like hands, or long stubs for arms). Characters are often shown super-deformed when characters get in comical situations. Often used interexchangibly with chibi, though technically, they're twoi separate, yet similar things.

SD

A abbreviation for "suck dick", it can be altered to correctly fit the sentence gramatically.

The term was originally coined by Aren, who used it with the letter M in the middle, rendering it SMD, "suck my dick".
